Yeah, you are right. You do have to cut the 61,000 in half. It's about 30,000(or 32 according to your data) per household.
It seems Ga. as a whole is somewhat low. But I guess the low cost of living makes such income levels usable/manageable.
I'll guess there are a lot of single people in Savannah, not to mention the poverty level may also be reflected in this statistic. And honestly, I didn't really state anything as a fact. I really believed that the average person in Savannah makes like 20-30,000. The 25 poverty level may seriously skew it left, however it would be very inaccurate if we excluded 25(give or take some) percent of the population. 16,000 is a bit low. It probably still falls below the state average. Savannah definitely needs some higher paying job oppurtunities. However, we need a well-educated population to attract such oppurtunities, meaning the school system needs to improve.
